Hoverflies (Syphidae), tribe Merodontini

Hard to see the linking factors in this tribe!

Eumerus tuberculatus Rondani 1857

Eumerus tuberculatus
  • Cambridge: 2 Sep 2001
  • Tentative identification - E. strigatus is very similar
  • Larvae feed on bulbs of garden Narcissus and (probably) wild bluebell
  • Detail - the venation near the wing-tips helps to distinguish this from other small dark hoverflies.

Large Bulb Fly Merodon equestris (Fabricius 1794)

Merodon equestris equestris Merodon equestris equestris
A range of colour forms but legs always black. These two are f. equestris with parti-coloured thorax, male (l), female (r).
Merodon equestris narcissi Merodon equestris transversalis
These forms with tawny thorax are f. narcissi (l) and the slightly different f. transversalis (r) with banded abdomen. There is also a form with black thorax.

Larvae feed on bulbs of eg Narcissus and bluebell so sometimes a pest.
